Introductory Background:

In the human body, the laminin 511 isoform is instrumental to the growth and maintenance of hPSCs through its binding to cell receptors a6B1 integrin. The iMatrix™ product line is based on over a decade's worth of work of Dr. Kiyotoshi Sekiguchi of Osaka University and his lab's research into the extracellular matrix. iMatrix-511 allows for single-cell seeding at low density, and the cells show high motility allowing clonal survival. The cells become tighter, are arranged in a monolayer, and can grow near confluence. iMatrix-511MG easily enables extended culture of human pluripotent stem cells. With nearly 500 peer-reviewed publications and growing quickly, it has quickly become a gold standard for stem cell culture.

Our unique technology allows us to utilize the Pre-Mix Method, where you no longer have to coat your plates before seeding your cells. You no longer have to worry about long curing times or plates drying out. It also saves you money as this method requires about half the amount you would need for pre-coating. Do more with less! And quicker! This also makes iMatrix-511 perfect for utilization in automated systems by reducing steps and simplifying processes, especially when combined with our Scraper-Free Method.

iMatrix-511 works in virtually any stem  cell line, from iPSC to hESC and MSC. It is also available in a clinical grade version, iMatrix-511MG, and a low-cost version grown in silkworm cocoons, iMatrix-511Silk, which combined with our unique pre-mix method, is cheaper per well in a six-well plate than Matrigel (~$2.00 per well vs. ~$1.60 per well).

The clinical grade version of iMatrix-511, iMatrix-511MG, meets the Standards of Biological Ingredients by Pharmaceutical and Medical Devices Agency (PMDA), a government agency in Japanese which is homologous to the FDA. .  The regulation is one of the strictest in the world and iMatrix-511MG not only fulfills regulatory requirements, it has since been used for a number of high-profile clinical applications in Japan.

iMatrix-511MG is also a GMP compatible and GMP adaptable resource. Our iMatrix™ products perfectly fit your workflow as you can easily move from basic research using our RUO iMatrix-511 to clinical use with iMatrix-511MG. With our clinical grade products you have the same versatility and benefits of our RUO products such as using the Pre-Mix Method saving you both time and money and the Scraper-Free Method increasing detachment efficiency and cell viability.
